“…Tailor made 3Y-TZP disc surfaces were as-sintered, polished, and sand blasted. Sandblasting is a clinically practiced surface roughening technique where abrasion with sharp airborne particles can potentially generate cracks a few micrometers deep together with some surface nano-roughening [ 7 , 8 ]. Studying the adsorption of salivary protein is important because it is the first step towards the formation of plaque and microbial adhesion [ 2 ].…”

“…An example of using an Al 2 O 3 coating is when Moritz et al applied a nanostructured alumina coating on a 3Y‐TZP ceramic surface in attempt to change the topography and surface free energy of the ceramic surface 95 . The alumina coating the authors deposited on the 3Y‐TZP surfaces had a thickness of a few 100 nm, and the research group found that a combination of sandblasting with alumina coating and thermal treatment had the optimal amount of osteoblast adhesion, proliferation, and maturation 95 …”

Surface modifications to enhance osseointegration–Resulting material properties and biological responses

As life expectancy and the age of the general population increases so does the need for improved implants. A major contributor to the failure of implants is poor osseointegration, which is typically described as the direct connection between bone and implant. This leads to unnecessary complications and an increased burden on the patient population. Modification of the implant surfaces through novel techniques, such as varying topography and/or applying coatings, has become a popular method to enhance the osseointegration capability of implants. Recent research has shown that particular surface features influence how bone cells interact with a material; however, it is unknown which exact features achieve optimal bone integration. In this review, current methods of modifying surfaces will be highlighted, and the resulting surface characteristics and biological responses are discussed. Review of the current strategies of surface modifications found that many coating types are more advantageous when used in combination; however, finding a surface modification that utilizes the mutual beneficial effects of important surface characteristics while still maintaining commercial viability is where future challenges exist.

“…Roehling et al demonstrated the lowest rate of bacterial adhesion after 72 h of anaerobic incubation on ZrO 2 surfaces when compared to other surfaces with similar treatment [ 19 ]. Similarly, processes aimed at nanotexturing ZrO 2 revealed a reduction in bacterial adhesion [ 107 ] ( Table 2 ). In addition, authors reported [ 108 ] the development of a surface based on Ti-coated alloy with a combination of cubic stabilized zirconia and silver films, significantly reducing the adhesion of bacteria such as Staphylococcus aureus and Staphylococcus epidermidis which are responsible for peri-implant pathology.…”

Oral Tissue Interactions and Cellular Response to Zirconia Implant-Prosthetic Components: A Critical Review

et al. 2021

View full text Add to dashboard Cite

Background: Dental components manufactured with zirconia (ZrO2) represent a significant percentage of the implant prosthetic market in dentistry. However, during the last few years, we have observed robust clinical and pre-clinical scientific investigations on zirconia both as a prosthetic and an implantable material. At the same time, we have witnessed consistent technical and manufacturing updates with regards to the applications of zirconia which appear to gradually clarify points which until recently were not well understood. Methods: This critical review evaluated the “state of the art” in relation to applications of this biomaterial in dental components and its interactions with oral tissues. Results: The physico-chemical and structural properties as well as the current surface treatment methodologies for ZrO2 were explored. A critical investigation of the cellular response to this biomaterial was completed and the clinical implications discussed. Finally, surface treatments of ZrO2 demonstrate that excellent osseointegration is possible and provide encouraging prospects for rapid bone adhesion. Furthermore, sophisticated surface treatment techniques and technologies are providing impressive oral soft tissue cell responses thus leading to superior biological seal. Conclusions: Dental devices manufactured from ZrO2 are structurally and chemically stable with biocompatibility levels allowing for safe and long-term function in the oral environment.
